sam AGENTS.md

Project instructions for SAM, a command-line tool that installs coding-agent configurations for several development tools. TDD means test-driven development, where tests guide implementation.

In plain words
What is it for?
They help test the command-line tool locally, target specific platforms, run formal test suites, and understand its templates and shared configurations.
Why use it?
They give coding agents the project structure and the commands needed to build, check, and test changes without guessing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

sam AGENTS.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

AGENTS.md - Agent Coding Guidelines for SAM

This file provides guidelines for agentic coding agents operating in this repository.


Project Overview

SAM (Smart Agent Manager) is an autonomous TDD agent system that generates agent configurations for Claude Code, Cursor IDE, Antigravity, and Gemini CLI. The project consists of:

  • CLI (bin/cli.js) - Node.js CLI tool that installs agent configurations
  • Templates (templates/) - Agent definitions in markdown format
  • Shared configs (_sam/) - Agent definitions used across all platforms

Build / Lint / Test Commands

Testing the CLI

# Test CLI locally (interactive mode)
node bin/cli.js

# Test CLI with specific platform
node bin/cli.js --platform claude ./test-project
node bin/cli.js --platform cursor ./test-project
node bin/cli.js --platform antigravity ./test-project
node bin/cli.js --platform gemini ./test-project
node bin/cli.js --platform all ./test-project

# Test with target directory
node bin/cli.js ./my-project
node bin/cli.js --platform cursor ./my-project

Running a Single Test

Formal test suites are available for specific platforms:

  1. Gemini CLI: npm test runs scripts/verify-gemini.js to validate skill generation.

Manual testing is done by:

  1. Creating a test directory: mkdir test-project
  2. Running the CLI: node bin/cli.js --platform <platform> ./test-project
  3. Verifying output files:
    ls -la ./test-project/_sam
    ls -la ./test-project/.claude/commands/sam   # for Claude Code
    ls -la ./test-project/.cursor/rules/         # for Cursor
    ls -la ./test-project/.agent/skills/         # for Antigravity
    ls -la ./test-project/.gemini/skills/        # for Gemini CLI
    

Publishing

# Publish to npm (requires authentication)
npm publish --access public --provenance

Code Style Guidelines

JavaScript (CLI)

Follow these conventions in bin/cli.js:

  1. Formatting
    • 2-space indentation
    • No semicolons at line endings
    • Single quotes for strings
    • Trailing commas in multi-line objects/arrays

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sam AGENTS.md is an instructions file published in the GitHub repository sam-agents/sam (18 stars, last pushed 1mo ago), licensed MIT. It adds 1,871 tokens to every session, about $0.0094 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
